Expression of Ideas practice question

Ancient Roman concrete was made with volcanic ash, which reacts with seawater so that the material grows stronger over the centuries. ____ some engineers today are experimenting with ash-based mixes designed to heal their own cracks.

Which choice completes the text with the most logical transition?

  1. A. Likewise,Correct
  2. B. However,
  3. C. Consequently,
  4. D. Nonetheless,

Answer: A. Likewise,

Both sentences describe concrete that improves itself through a chemical reaction — the ancient case and a modern parallel. A transition of similarity fits.

Why the other answers are wrong

B. However,
'However' signals contrast, but the modern experiments follow the same idea as the Roman concrete.
C. Consequently,
'Consequently' would make the modern work a direct result of Roman concrete. It's inspired by it, not caused by it — and the sentence presents a parallel, not an effect.
D. Nonetheless,
'Nonetheless' means 'in spite of that'. Nothing in the first sentence is an obstacle to the second.
